1. Balancing groups are virtual energy volume accounts that allow electricity market players to balance their actual feed-in and offtake within a control area.
2. Customers receive electricity supply in balancing groups. Balancing groups can withdraw and/or add capacity. The manager of a balancing group ensures that the balance of capacity in the balancing group is equal in every 15-minute period measured. This means balancing capacity for overall demand on the one hand and overall supply on the other.
